HARSH ENVIRONMENT RATCHET COUPLING M SERIES CONNECTOR Rapid ratchet coupling mechanism The M Series connector offers a new innovative design for motorsport applications and military systems. Made of high-strength aluminium, this connector is one of the lightest and most compact connector of the LEMO range. A ratchet screw system enables quick and secure coupling of the connectors. The arctic grip makes it easy to manipulate the connector while wearing winter gloves or when the connector is located in a difficult to access area. Features * Ratchet-coupling mechanism * Quick mating: 1/2 turn to seat * Compact design for space savings * Oil and fuel resistant * High vibration and shock resistance (gunfire test) * 360 screening for full EMC shielding * Sealed to IP68 when mated * Colour coding / keying * Requires 2x the coupling force to unmate * Scoop proof * Reverse sex configuration possible Technical Characteristics Characteristics Endurance Operating temperature Resistance to vibration Shock resistance Salt spray corrosion test Protection index (at 2m, 30')1) Gunfire Material and treatment Value Standard Characteristics 3000 cycles -50C/+200C 10-2000Hz, 15g 100g, 6ms 144h IP68 satisfied IEC 60512-5 test 9a - IEC 60512-4 test 6d IEC 60512-6 test 6c IEC 60512-6 test 11f IEC 60529 MIL STD-810-E Value Outershell, coupling nut Earthing crown Ratchet Insulator Contacts Gaskets Sealing resin Surface treatment Ni (5 m)2) Au (1.5 m) - - Ni (3 m) + Au (1 m) - - Aluminium (AA 6262A) Bronze (UNS C 54400) PEEK graphite PEEK Brass/Bronze FPM + FVMQ Epoxy Note: 1) at 1.8m/15h. 2) Anthracite colour.
